The general object of the invention is 'tov provide an indicating attachment olf the' characterreferred to havin g various characH teristies and. advantages, among iviiiciiare the following: The attachment may "ne 'ea-Zdily applied to standard 'typewriter machines use or embodied in the machine-at the itac tory; the' device is applied. to tlie niacliineijy securing the casing` to the .traine of tne typey writer and the prime moverte theaxle of the pieten relier; the attachment presents' a neat appearance; the index 'ineens issucii as to indicate the number of lines typed and thisv` regardless of wlietlier the Writing be single5 double-,or tripie space, or 'any coinbination oi these; the indicating ine-ans in clude-s pointer and dial7 one inoveiiie relatively 'to 'tlie other5 either tlie dial being' .arranged to turn relatively to the pointer, or

vice versa; ineens is `urovir'ied to set the dicating-nieans by inanuai turning' oit the 'diei or pointer5 according,` to. which is 'arranged to turn, and 'the 'setting may be done before inserting the paper or after the ne per has been inserted in the machine, the operator noting at what point the indicator should be set depen g upon the piace the pa per occupies in the typ-e T.riter at lthe eine the setting is done7 whereupon the device automatically registers for indicates tlie exact number oi" lines which may still be written on the ui'iused portion of the paper; by inf dicziting the number of unused lines 'the indicator means enables the operator to readily calculate tlie number oi lines 'that have been Written.

'1era fsm-iai no. :ii/isti] attachment iliustrating 'the saine applied to a typewriter shown in part; l Fig. 2 is'e longitudinal vertical section .The letter A. indicates the usual axle of the platen roller B, and C indicates the adjacent portion oi the typewriter frame. f In carrying out my inventi.on,"a. part 10. is provided to be attached. to the axlelA, said part as seen in Fign 2, being tubular for its' major portion to tit over said arl-e and it is secured 'to the latterjby any suitable means as for instance,.set screws 1l. The member 10 is provided with an operating element to be gresped'by tlie'user and this .n'iayconsist as indicated at 12 of the usual 'rniiled handwlfieei which' ordinarily 'is directiy applied 'to the aided@ lie prinemover 13er initial drive element of tne .gearing for the 'indicator means 'is in fixed relation' to the axle 'A and here is siioivnas integral with the tubular portion ot the element .10.. Said drive member 13 is .here si'iown as a gear Wlieeland it is in driv ing engagement with a second' Wheel 14 loose 'on' a stud shaft 15, saidshaft being vsecured to a flange 16 on a casing 17. The casing iangel -is secured to the frame vC ofthe typewriter-.by any suitable means such as Sei'eWS, one of which is indicated 'at 1237k Fig.' 2.- Integrai' with or otherwise in iXed relation tothe'driven Wheel 14C is awheel 19 which in'turn'isin driving` engagement with a 'Wheel 2)', tli Wheels v19-aiid 20 in the Atorni illustrated .in Fig. 21 being bevel gear Wheels. The turningoi' the Wheel 20 gives relative movement te a dial and pointer, one of which is actuatedbyf said Wheel 20.

Obviously, eitlier the pointer or dial may.

revolve in practice .in .responseA to the turn# ing et tlie drive Wheel 13 With the platen axle it.. in the form shown in Fig. 2, the dial, 22, is adapted to be turned, said dial beingniounted on a sleeve 21 which at one .end constitutes a bushing in the hub of the driven -vvlieei 20. The pointer 23 is secured to theend oi a spindle 24 which extends through the bushing 21. In front of the dial and pointer 'is a glass .front 25 resting)r one head2@ and secured by a clamp ring 27 threaded onto the cylindrical top portion of tlfier casing 17. 0n the spindle 24: at the opposite end from the pointer 23 means is provided for manually turning the spindle and tlie pointer for Setting the indicator. The setting; means in the present instance in- .cludes a pinion 28 on the spindle 24 and in engagement with a iinion 29 on the counten shaft 30 supportey in the casing 17, said.

shaft 30 having-a milled wheel 31er equivalent handleelement. The manner of setting inpractice depends on Whether the indicating meansprovides for turning the' pointer or the dial. In any event the setting of the indicator to establish the proper relative positions of thepointer and the markings onthe dial can .be-effected before the paper is inserted in the 'machine by turningthe axle A andthe indicator drive means, or

- vthis may be done by turning the handwheel Aao 31 which permits of setting the indicator after the paper has been inserted in the machine. 4,In the operation of the device when the axle A and the platen roller 'are turned,4

the drive yelement 13 will turn at thesame speed. Said drive element-13 in turn actuates the Wheels 14:,v 19, and 2 0, the latter giv ing movement to either the dial or pointer, in thisinstance the dial.' Thus, by properly calculated gearing.v for each line space which vthe typewriter platen turns, the.drivev wheel lturns'in a similar direction at a corresponding speed, the-movement being finally transmitted tothe dial whichi-in turn moves a corresponding distance.

The dial 22 -preferably'is marked as shown in Fig'l with three annular concentric zones or circles ofdivisions and numbers. Each subdivision onx'the outer or largest circle corresponds to one singlespace'turn of the laten; the Imiddle' zone or circle indicates' y veach subdivision, one double-space turn of the platen; Whileeach division of the smallest or inner circle indicates one triple space turn of the platen. Thus, itis seen that the outer circle is divided into siXty spaces, the middle one into thirty spaces, andthe inner circle into-twenty spaces or the ratiol of three of the first toi'one of `the last being thel proportion-of the-single'to the triple spacing.

I would state in conclusion that while the illustrated example constitutes 'a practical embodiment of my, invention, I do not limit myself strictly tothe mechanical details `herein illustrated, `since manifestly the same can beconsiderablyvaried without departurefrom the'spirit of the invention as definedin the appended'claims. For example, the number of driven elements `in the drive gearing supported bythe 'casing for actuating the indicating means andthe character of the ldrivenv and drive elements may -fbe varied, as may-also the particular-means for giving relative movement :to 4the pointerjor lhaving driving connectionwith said drivenelement, and drive mean connected with said spindle, said spindle being adapted to be turned by the last-mentioned drive means and relatively to said driven element for setting the turna-ble indicator'device independently of said driven element.

2, A typewriter attachmentof the class4 described includin indicator means com-' 7 prisin'g a pointer and'dial, actuating means for one of the same, means-adapted to be secured to the axle of the platen. roller to drive said actuating means, .a drive/train fcrone vof the indicating elements, and a spindle adapted to be driven by said drive train and vcarrying that indicating element to be actuated, said drive train being manually operable to set .the last mentioned :indicator means and first-mentioned drive element.

3. An attachment for typewriters to indicate the number of lines remaining to lbe written on the papel' in the machine, the same including an indicator dial and a pointer, the .one adapted to turn relatively tothe other, and means to drive the turnablei indicating element with the turning of e platen roller, said dial presenting three concentric Zones bearing subfdivisions corresponding respectively to single, double' and triple' line spacing. l

4a An attachment fdr typewriters to indicate the number of'lines remaining to be- Written on the paper in the machine', the same' including an indicator' dial and a pointe`r,'the one adapted to turn relatively to the other, and 4means to drive the turnable indicating element with the turning of the platen roller, said dial presenting three coni centric zones, the outer zone being' divided intov sixty subdivisions, the intermediate zone into thirty s'lil: -divis1ons, andthe inner.

'zone into twei'ity sub-divisions.
